IMPRCVEMENT IN LEA'THER-RO'LLING MACHINES.l

Specication forming part of Letters Patent No. 194,352, dated August 21, 1877; application tiled June 18, 1877.

To all whom it may concern:

Be it known that I, HENRY HUDSON, of Saltillo, in the county of Huntingdon and State ot' Pennsylvania, have invented a new and useful Improvement in Steam-Pressure Roller for Rolling Leather, of which the following is a speciiication:

Figure 1 is a side view of my improved apparatus. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved leather rolling apparatus which shall be so constructed as to enable the pressure to be applied by steam-power, and which shall be simple in construction and easily controlled.

The invention will first be described in connection with the drawing, and then pointed out in the claim.

A representsthe frame of the machine. B is the table, and C is the concaved block, upon which the rollerworks. D is the roller, which is pivoted to the lower end of the swinging bar E. The upper end of the bar E is pivoted to the free end of a spring-bar, F, the other end of which is attached to the frame A.

' To the spring-bar F, at alittle distance from its free end, is pivoted the upper end of a short connecting-rod, G, thelower end of which is pivoted to the lever H. One end ofthe lever H is pivoted to the frame A, and with its other end is connected the piston-rod I, the piston of which works in the steam-cylinder J. With the head ofthe cylinder J is connected avalvechamber, K, through which steam enters from the pipe L, and is exhausted from the said cylinder J through the pipe M. With the valve-stem N is connected the short arm of the bent foot-lever O, which is pivoted at its angle to a support attached to the iioor. The free end of the lever O is held up by a spring, P, placed beneath it. Y

With this construction, when the free end of the lever O is pressed down, steam is admitted to the cylinder J, which ,forces down the piston and applies pressure to the roller l D. When the foot is removed :from the lever O the said lever is raised by the spring P, which closes the inlet and opens the exhaust, and the piston and the roller D will be raised by the spring F. The ,bar E is vibrated to roll the leather in the usual way. f.

Having thus described my invention, I claim `as new and desire to secure by Letters Patenttion of the steam piston-rod I with the lever H, connecting-rod G, pivoted bars E F, and roller D, all substantially as and for the purpose specified.

i HENRY HUDSON.
